A Cu loaded NiFe layered double hydroxide bifunctional electrocatalyst with a coupled interface structure for both the nitrate reduction reaction and oxygen evolution reaction

We present an interface coupling strategy using Cu nanoclusters and NiFe LDH nanosheets to form a heterostructure electrocatalyst (Cu/NiFe LDH) and apply it as both NO 3 − RR and OER bifunctional electrodes under ambient conditions.
